i would buy a plug and wire it. but you can wire it str8 to the tube. wire it color to color. they should have the same color wires on both units.

Problem solved.

Glad you figured it out,I couldn't help but lol the whole time.

I was thinking hammer drill and chainsaw might get involved.

May I suggest a boxed junction with 3/8 clamp connectors in the 1/2" knockouts and bond the ground conductor to the metal box and blank cover of course.
